Microchip, 16 bit Digital Signal Processor 70 MIPS 256kB FLASH 64-Pin TQFP

dsPIC33EVxxxGM00x/10x 16-Bit Digital Signal Controllers

Microchip’s dsPIC33EV family of 16-bit Digital Signal Controllers (DSCs) features a 70 MIPS dsPIC® DSC core with enhanced on-chip features. Capable of operating in harsh environments these devices are suitable for appliance and automotive applications. Rich peripheral integration includes SENT (Single-Edge Nibble Transmission-Transmit/Receive), High Speed PWMs, OP Amps and Error Correcting Code Flash for increased reliability and safety. The performance offered by the dsPIC33EV family of MCUs allows them to be incorporated into the design of high-performance, precision motor control systems that are more energy efficient. They can be used to control BLDC, permanent magnet synchronous, AC induction and stepper motors.
